paging file or a scratch partition‚ and the combination of physical Ram and the paying file form the system’s total memory. When the system runs lows on physical memory‚ it can “swap” portions of RAM to paging file to make room for the new data‚ as well as to read previously swapped information back into RAM. Excessive use of this mechanism results in thrashing and generally hampers overall system performance‚ mainly because hard drives are far slower than RAM. Software can “partition” a portion of a
